This invention relates to railway rolling stock and consists particularly ina novel construction of side or end sills for 'carunderframes and the assembly therewith of the car walls and floor. In ordinary construction the car ioor rests on top of the underframe sills and abuts against the inner face of the car wall, forming a joint which usually results ina crevice within which coall dust, cinders, other dirt, and water may accumulate. Sulphuric acid and other corrosivel agents from these de posits attack the adj acent'portion of the wall especially where the wall is composed ot metal plates, necessitating repair and renewal of the Wall.

The main object of the present invention is to provide an underfraine having a no vel sill structure including an element extending above the level 'of tlie top surface of the floor and arranged for attaching the wall so that the joint between the latter and its mounting member is spaced-above the fioor, thereby avoiding the objectionable crevice and resultin corrosive action referred to above.

urther objects of the invention are to pro# vide a strong, rigid, economical underframe structure adapted to readily mount the car walls and associated framing with` a minimuni amount of machining.

I attain these objects and others in the structure illustrated in the accompanying drawings in which- Figure lis a partialtop view of an underl frame embodying my invention.

Figure 2 is aside View of the same.

Figure 3 is a vertical transversey section taken on lines 3.3 of Figure 1 andshowing riti portion of the side framing, side wall and oor.

Figure 4 is a section illustrating a modified structure.

The underframe illustrated is of cast metal construction and the portion shown includes a centerr sill 1 and transoms 4 of I section, a box shaped bolster 2, and angular side sills 5 and an end sill 3. At the intersectionof each transom 4 and bolster 2 with the side sills 5, enlargements or gussets 6 are provided for attachment of suitable side framing 13.

nach sid@ siu'compri'ses a veaiciweb s and includes a horizontal ange 7 for directly supporting-the floor boards 9. Ribsl 10 and 14 are' provided at theA intersection of `each transverse member with the side sill for assisting in maintaini'ngthe rigidity of the structure.

The vertical web S-extends upwardly above flange 7 for a distance insuringA its rojectii above the top of a ioorwhch may carri on the flange. The car side wall 12 overlaps the outer face of web 8 and is bolted,`

riveted or welded to the upper: portion thereof and is spaced from the floor 9. Preferably, web 8 is' recessed, 'as indicated at 11, to permit the outer face of wall 12 to be alined withv the outer face of. the body of web 8 whereby the ramin 13 may be applied to the silland the wal without any offset to accommodate the wall as would be required if the wall projected from the face of the sill.

With this construction any moisture orv dirt tending to collect at the corner between the oor andwall cannot affect the side wall because of the intervening projection 15 ofv the sill. Most of the moisture will drain between the ioor and the projection 15 and over H zige 7 so as to avoid undue corrosion` on this si The sill will be of greater thickness than the side wall and any corrosive action will be resisted b the sill for a substantially greater period o time than' such action would be 'resisted by the relatively thin side plates.`

The floor may be of steel aswell as wood and the side wall'may be ofwood aswell as steel and 4Figure 4 illustrates: a modied structure in which the angular sill has an upwardly extending rib 21. oiset from the depending leg of the sill for attaching the side wall 22 and the inwardly extending leg of the sill supports the metal floor plate 23.`

As in the previously described structure,

Vthere isl no crevice between the floor and the side wall and anymoisture running down the wall and between it and flange 21 will drain over the sill and not be retained in a pocket to set up corrosive action on the wall.

In this structure the flange 21 is offset inwardly a substantial .distance from the Cil outer face of the sill so as to accommodate the relatively thick wall boards and leave their outer faces iiush with the outer face of the sill so as to utilize a straight framing member 24.

Obviously, both Hoor and wall may be of wood or of steel plate and various other' changes in the details of the construction may be made without departing from the spirit of the invention and I contemplate the exclusive use of suchv modifications which come within the spirit of my invention as expressed in the claims. v

I claim: c v

l. A sill for railway vehicle underframe including an element for mounting fiooring and a member projecting substantially above said element for attachment of an upright wall above the level of the top of the fiooring.

2. In a sill for a railway vehicle underframe, a vertical web arranged to mount a side wall on the exteriorface of its upper portion, and a liange projecting inwardly from said web for mounting a floor below Vthe top of said wall mounting portion.

3. In a sill fora railway vehicle underframe, an upright element adapted to mount a vehicle wall on its outer face, and a member projecting from its inner face for mounting a vehicle floor.

4. A sill for a railway vehicle underframc including a substantially horizontal fiange for mounting flooring, and an upright web adapted to mount wall material on its outer face, said sill being shaped to prevent extraneous particles from being trapped between said flooring and said wall material.

5. In a railway vehicle, a framing sill having horizontal and vertical webs, fiooring mounted on said horizont-al web, and an upright wall attached to the outside of said vertical web, said vertical web being extended above the level of the top of said flooring and adapted to prevent extraneous material accumulating on said iooring from contacting with said wall.

6. In a railway vehicle underframe, a transom, aside sill, and'a reinforcing rib at the intersection of said sill and said transom, said sill including an inwardly extending horizontal fiange merging with the upper surface of said transom and adapted to mount fiooring, and an upright web extending above the upper surface of said flooring and arranged for attachment of an upright wall to space the same from said flooring.

7. In a railway vehicle underframe, a transom, a side sill, and a gusset projecting from said sill adjacent its intersection with said transom and adapted to mount a side frame member, the upper surface of said transom being adapted to mount flooring, and said sill including a vertical web merging with said gusset and having its upper surface and spaced from the upper surface of said flooring for attachment of a side wall.

9. In combination in a railway Vehicle, a transom including an upright portion and a horizontal flange adapted to mount iiooring, a sidc sill including a vertical web, a gusset located at the end of said transom and merging with said vertical web, a reinforcing rib extending between said usset and the lower edge of said transom, saidl gusset and vertical web cooperating to form a surface for mounting a sideframe member, and a wall attached to said side frame member and said vertical web, said vertical web intervening between said wall and said fiooring.

l0. In a railway vehicle, an under frame sill, a iioor supported thereby, said sill having an element projecting above the level of said fioor for attachment of an upright wall with the joint between said element and wall above said floor.

.12. In a railway vehicle, a cast metal sill having a substantially horizontal flange and an upright web, a sheet metal wall secured to said web, flooring mounted on said Harige, said web being located between said wall and said flooring to prevent corrosion of said wall due to deposits of matter between saidy flooring and sill.
